Seen that too, I tend to blame the compositor though. There are known
issues with the server-side one, not sure about the userland one, it
seems to have a problem with minimize/maximize when using drop shadows
at least.

I get this weird slowdown too. I haven't investigated yet and I don't
really have a firm reprocase. It happens usually want to show somebody
how cool EXA is :) A given window suddenly becomes very sluggish to move
around. Sometimes, just switching workspaces and back, or focusing
another window and back or that sort of thing "fixes" it iirc.

Interesting (the drawing artifacts that is).
